Title: Improvements in the production of viscous aqueous alkaline solutions of vegetable globulins suitable for conversion into artificial filaments
IPC: D01F4/00
Filed: 1945-04-09
Abstract: <PICT:0590002/IV/1> <PICT:0590002/IV/2> A viscous homogeneous aqueous alkaline solution of a vegetable globulin adapted for conversion into filamentary products is produced by progressively converging under conditions excluding the introduction of air, and at appropriate relative rates of delivery, small elements of an aqueous suspension of vegetable globulin and of the aqueous alkaline solution, such that the mixture will contain the required final concentration of vegetable globulin and of alkali, into a region wherein these elements are mixed under turbulent conditions excluding the access of air.  The resulting solution is progressively withdrawn and may be aged to a predetermined viscosity for a fixed temperature by passing it at a regular rate of delivery through a zone heated by means viscostatically controlled by variation in viscosity in a continuously and progressively renewed fraction of the resulting aged solution brought to a fixed lower temperature as described and claimed in Specification 579,089.  It is advantageous to have the vegetable globulin present in the aqueous suspension at its isoelectric region and to have the alkali concentration such that when freshly mixed, the vegetable globulin solution has a pH of at least 12.5.  The length of the converging columns are desirably such that they prevent the access of air to the mixing region.  In an example, vessel 1 contains a water cream of oil-freed peanut globulin at its isoelectric point and vessel 4 contains the sodium hydroxide solution.  These vessels are each connected through meter pumps 5 and 51 respectively to the turbulent flow device 7.  The pressure of the liquids passing through the constricted tube 9 lifts the ball of the spring-loaded ball valve from its seating, thus causing a narrow opening which permits the liquids to pass into the wide tube 10. Specification 537,740 also is referred to.

Title: Improvements in or relating to drying drums for use in drying material in the form of small pieces
IPC: F26B11/04
Filed: 1947-03-31
Abstract: 653,384. Drying apparatus. AIR CONTROL INSTALLATIONS, Ltd. (Aktiebolaget Svenska Flaktfabriken). March 31, 1947, No. 8709. [Class 34(ii)] A drying drum for drying material, e.g. chopped grass, is rotatable on its horizontal axis and is separated along its length into two zones separately supplied with drying medium which flows in the same direction as the material in both zones. As shown, the material to be dried, carried on a conveyer 4, and gas from the furnace 1, enter the drying zone A, in section 5 of the drum, at 2, the material being picked up by scoops 6 having bent over tips, the angles between the tips and the main parts of the scoops varying along the length of the section. The material enters the drying zone B in the section 14, which slidably engages the section 5, and is provided with scoops 17 and a gas inlet 18 for drying medium at a lower temperature, by pipes of a sluice 8 while drying medium, and light particles carried by it, issue from section 5 by a central aperture in the plate 10 to enter, the channel 15 between the sections and the compartment 23 of a stationary box 21. The compartment 22 of the box 21 is in communication with the interior of zone B and particle-laden gas from both compartments is sucked by a fan 27 into a cyclone 30 which separates the material, which is returned to section 14 by the pipe 31 and conveyer 32, from the gas, which is discharged through the outlet 33. The dried material from section 14 drops into compartment 22 from which it flows to a vertical pipeline connected to a cyclone separator 35 from which the dried material drops into the receiver 38 from which it may be filled into sacks. The two supplies of drying medium may be derived from the same furnace and in a modification the two drying zones are not separated by a sluice device, the hot gases flowing from the first to the second zones mixing with a fresh supply of hot gas from the furnace at the junction of the two zones.

Filed: 1976-03-04
Abstract: 1527652 Rotatable needle carriers NEWROYD Ltd 17 Feb 1977 [4 March 1976] 08752/76 Heading D1G A machine for making a textile product with a reciprocatable needle carrier shaft and means with a first motor to forward yarn to a needle carried by the shaft has programmed control means to rotate the shaft to predetermined angular positions such that while the needle carrier moves relative to a base material by means of second and third traverse motors, when the direction of movement changes the shaft angle is altered to maintain the same portion of the needle always facing forwards, the programmed control means being influenced by the speed of reciprocation of the needle carrier and controlling the first, second and third motors. As shown in Fig. 6 a cylindrical cam 85 is rotated by air motor 84 to generate reciprocation of the needle carrier shaft. Gearing from the shaft of cam 85 is provided to rotate the needle carrier in either direction selectively as determined by clutches responsive to the control means which also operates a brake to retain the selected angle. The actual angle is determined by a perforated disc cooperating with photosensors and compared by the control means with a desired angle determined from the lateral movement of the needle carrier. A perforated disc 14 cooperating with a photosensor generates a pulse signal proportional to the needle reciprocation on which all of the control is based. Fig. 5 shows a cable system whereby a needle carrying head 9 is traversed orthogonally over a work piece by servo motors 75, 83. Yarn is fed by an air stream through duct 102 which is directed along the hollow needle 22. Forwarding roller 111 driven by servomotor (the first motor) 112 pays out yarn under the influence of the control means. The described embodiment is a tufting machine but the invention is applicable e.g. to embroidery machines or machines for stitching fabric together.

Title: Improvements in or relating to planographic systems of reproducing multiple copies
IPC: B41M5/025
Filed: 1953-03-31
Abstract: 737,605. Transfer paper &c. DICK CO., A. B. March 31, 1953 [May 13, 1952], No. 8950/53. Class 96. [Also in Group XVI] A method for the production of copy with a master is characterized by forming a planographic image on the master with a composition substantially free of dye colour and containing at least one of the components for reaction to form a dyestuff, wetting the surface of a copy sheet with a fluid containing a solvent for the dye-forming component, and contacting the wetted surface of the copy sheet with the imaged surface of the master to dissolve off some of the dye-forming components to the wetted surface of the copy sheet for reaction to form the dyestuff in the imaged areas of the copy sheet. The dye-forming components may comprise a diazo dye-forming component and a coupler which reacts therewith to form an azo dye. The diazo dye-forming component may be coated on a transfer sheet from which the master sheet is prepared and the coupler may be impregnated in the copy sheet or be contained in the wetting- out solution in which the dye-forming component in the master is soluble. Alternatively the coupler may be coated on the transfer sheet and the diazo dye-forming component contained in the copy sheet or in the wetting-out fluid. In a further alternative, both dye-forming components may be present in the imaged master sheet, in the presence of an acidic medium which maintains the pH value below 3.5, the components being selected so that at a pH value below 3.5, inter-reaction is impossible. An alkali solution, to increase the pH value above 3.5, is then contained in the wetting-out fluid or the alkali may be applied to the copy sheet after application of the wetting-out fluid. The diazo dye-forming component is of the general formula In an example the carbon transfer sheet is formed by coating a thin fibrous sheet with a composition of carnauba wax, oxidized microwax, polybutene, petrolatum, mineral oil, and 20-75 per cent by weight of para diazo diethyl aniline zinc chloride. The composition is melted at a temperature of 80-85 C. and applied on the surface of the base sheet in concentrations from 15-20 pounds/3000 sq. feet. The fluid applied to the copy sheet is composed of 0.5 per cent phloroglucinol, 5 per cent #- naphthol, 2 per cent diethanolamine and 92.5 per cent methanol. Coupling to form a permanent azo dye takes place between the para diazo diethyl aniline zinc chloride and the phloroglucinol and #-naphthol, the pH level being adjusted by the diethanolamine.

Title: Process for the manufacture of dyed artificial fibres or films from cellulose esters
IPC: D01F2/28
Filed: 1931-03-25
Abstract: Artificial fibres and films are prepared from solutions containing a cellulose fatty acid ester and an enolic substance or substance containing a phenolic hydroxyl group capable of being coupled to form azo dyestuffs.  The fibres or films may then be dyed by coupling the enolic or phenolic substances contained therein with diazo compounds by the customary methods.  The components for the manufacture of the azo dyestuff are preferably chosen so that neither contains a group inducing solubility in water.  The following examples are given:--(1) A solution of cellulose acetate in acetone and alcohol containing one of the following additions, is spun by the dry-spinning process -2-3-hydroxynaphthoic acid anilide, b -naphthol, 2-hydroxycarbazole-3-carboxylic acid-4<1>-chloroanilide, di-acetoacetic acid-o-toluidide, or 1-phenyl-3-methyl-5-pyrazolone. (2) A solution of cellulose acetate in methylene chloride-alcohol containing 2-3-hydroxynaphthoic acid anilide is spun.  (3) A solution of cellulose acetate in acetone and alcohol containing 2-3-hydroxynaphthoic acid anilide is used to prepare films.  (4) Artificial silk prepared as in (1) is treated in a bath containing m-aminoazotoluene hydrochloride.  Diazotization then follows in a bath containing sodium nitrite and hydrochloric acid, after which coupling is completed in sodium acetate solution.  The azo compound may be replaced by 3-chloroaniline for orange, or 2-5-diethoxy-5-benzoylaminobenzene for deep blue shades.  (5) Acetate silk containing 1-phenyl-3-methyl-5-pyrazolone is coupled with o-chloroaniline hydrochloride as in (4).  (6) A film containing 2-3-hydroxynaphthoic acid anilide prepared as in (3) is coupled with 4-chloro-2-aminoanisol hydrochloride as in (4).
